I'm still trying to isolate the cause of frequent hard crashes. Studying
Event Viewer (a daunting experience that never fails to depress me)
shows a bunch of vague possibilities to pursue.

One is Event ID 7000, "The CldFlt service failed to start due to the
following error:
The request is not supported." This occurred either just before, during
or just after the latest such crash (which always need a forced
restart).

But I don't see such a service listed on my Win 10 Pro PC!

So naturally I cannot try the suggested fix he

Insights anyone please?
